The PXN has fallen from a high level, and the PX - MX spread has also declined but remains at a high level. Future Asian PX supply will gradually increase [3][4]. - PTA: Cost support is weak, and there is negative demand feedback. Attention should be paid to warehouse receipt pressure. The unilateral trend is weak, and short positions should be held. The spot processing fee remains low, and the basis and monthly spread are both weak [5]. - MEG: The unilateral trend is weak, and attention should be paid to the opportunity of positive monthly spread arbitrage. The profit of coal - based MEG plants has recovered, and the production of some ethylene oxide plants will be converted to MEG in the future [6]. Summary by Directory PX Valuation and Profit - PX unilateral price has dropped significantly, and the structure has gradually become flat. The PXN has fallen from a high level, and the PX - MX spread has also declined but remains high.

There is no new PX maintenance in China in August, and some plants are restarting. Future Asian PX supply will gradually increase. PTA device operating rate is expected to decline in August, which means reduced demand for PX [3][42]. Inventory - In July, the monthly PX inventory in Longzhong dropped to 414 tons (-24) [65]. PTA Valuation and Profit - The spot supply is increasing, the basis is in a reverse arbitrage situation, and attention should be paid to the opportunity of positive monthly spread arbitrage at low levels. The spot processing fee remains at a low level, and some plants have unplanned maintenance [71][82]. Supply and Demand - The PTA device operating rate remains at 75.3% (-4.4%) and is expected to continue to decline in August. Some plants have stopped production or reduced loads.
